Apps should not be twiddling with tunables in /proc or /sys - they are system wide attributes.
Agreed, but many applications need some tunables to be set higher than the default values. So, today, there must be administrators doing an "echo xxx > /proc/kernel/sys/yyy", either by hand or via a script. This is only what the libtune is intended to do.
It is an administrator issue - they are the only ones who can arbitrate between the needs of different apps.
It's never the sort of thing which will be in Fedora base, or RHEL, and therefore any app that would want to use it would need ot have code to handle it not being there anyway. So, what's the point?
Yes, if it got into only one then there'd be little point. However isn't it safer to have a migration path? There'd be a period where an app would use both libtune and its own code. Then, once libtune is in both Fedora and RHEL,
Re-read above please. It's *never* going to be in the Fedora base distribution or RHEL, as the upstream kernel and development community has rejected it as a way of doing things.
